To study the chemical constituents in the active portion from the flowers of Polygonum oriental.
Chromatographic techniques were employed for isolation and purification of the constituents and their structures were determined by spectral analysis and chemical evidence.
Nine compounds were obtained and identified as alphitonin (1), methyl 3, 4-dihydroxybenzoate (2), apocynin (3), kaempferol-3-O-beta-D-glucoside (4), 1,3,5-trihydroxybenzene (5), 3,3'-dimethoxyellagic-acid-4-O-beta-D-glucoside (6), kaempferol-3-O-alpha-L-rhamnoside (7), quercetin-3-O-alpha-L-rhamnoside (8), kaempferol (9).
Compounds 2, 4, 5 were isolated from P. oriental for the first time and compounds 1, 3 were firstly obtained from the genus Polygonum.
研究东方蓼花活性部位的化学成分。
采用色谱技术对成分进行分离纯化，并通过光谱分析和化学证据确定其结构。
得到9个化合物，分别鉴定为α-衣康酸（1）、3,4-二羟基苯甲酸甲酯（2）、阿朴菲宁（3）、山柰酚-3-O-β-D-葡萄糖苷（4）、1,3,5-三羟基苯（5）、3,3'-二甲氧基鞣花酸-4-O-β-D-葡萄糖苷（6）、山柰酚-3-O-α-L-鼠李糖苷（7）、槲皮素-3-O-α-L-鼠李糖苷（8）、山柰酚（9）。
化合物2、4、5首次从东方蓼中分离得到，化合物1、3首次从蓼属植物中获得。
